Alternative slang for what most would commonly refer to as a laptop or notebook and/or netbook computer. But could also extend to an iPAD as well. It is derived from THE SPRAWL Trilogy (*this includes the short stories Johnny Mnemonic, New Rose Hotel, Burning Chrome) of Sci-Fi Cyberpunk novels by William Gibson (Neuromancer, Count Zero, Mona Lisa Overdrive). ---basically, die hard fans and wishful thinkers who are bored/disappointed with modern tech as it exists now (such as a smart phone) for being too practical and lacking imagination, and have labeled things in the manner of the alternate 1980s of Gibson's Cyberpunk world line; and in a sense, sticking to more cumbersome (and often times outdated) tech in contrast to what is accepted by the collective majority. Thus some might flip open a laptop/note book and log onto the Internet... others will power up their Cyberdeck and jack into Cyberspace.

Case: "My dumb phone handles my calls... but I still lug around my Cyberdeck to get online."
